Answer:
There is no solution.
Rewrite -2x + y = -6 so it starts with y =...
y = 2x - 6
Substitute that in 2/3x - 1/3y = -2 gives:
2/3x - 1/3*(2x -6) = -2
2/3x - 2/3x + 2 = -2
0 + 2 = -2
This statement is not true, and that means there is no solution.
Answer:
B. x=6
Step-by-step explanation:
substitute -7 into 2y to get -14. your new equation should be 4x-14=10. add 14 to both sides to get 4x=24, divide both sides by 4 to get x=6.
Lemme post a quick template of some help
so f(x) - k, is simply appending a constant "k", and thus is a vertical shift by
k units.
f(x+h) is changing whatever "x" was to "x+h", and therefore is shifting the function to the left by
h units.
f(x-h), is about the same as before, but is doing a horizontal shift to the right by
h units.
